FIG. 4 is a cross-sectional view taken FIG. 3; and
FIG. 5 is a cross-sectional view taken along 5-5 of FIG. 2 and drawn to an enlarged scale.
diagrammatically in along line 4-4 of DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and particularly to FIG. I, a gas turbine has been shown generally at having an air intake 12, a suitable compressor 14, a combustion chamber 16 where fuel is introduced and burned, a turbine 18 adapted to be driven by the hot gas stream formed in the combustion chamber 16 and a suitable discharge nozzle 20.
The manifold spray assembly of this invention has been shown generally at 22 secured to the forward or intake end of the gas turbine I0 by means 24 which enable the spray assembly to be readily removed and replaced.
Referring now to FIG. 2 the manifold spray assembly 22 has been shown as comprising an annular housing or support ring 26 formed with an axial bore 27, means for spraying or directing a liquid or suitable fluid generally radially inwardly and axially rearwardly of the support ring axial bore 27, and means 28 for delivery of a liquid or suitable fluid to the spray means.
The means for spraying or directing a liquid or fluid includes four nozzle assemblies 30, 32, 24, and 36 respectively comprising a first nozzle 38 and a second nozzle 40 suitably secured to a nozzle support block 42 in a position communicating respectively with passages 44 and 46 formed in each nozzle support block.
The nozzles 38 and 40 extend generally radially into apertures 48 formed in the support ring 26 but do no extend beyond the support ring axial bore 27 and hence do not interfere with the gas turbine inlet airstream.
' 68 with nozzle support block passage 46.
Each nozzle 38, 40 is fonned with an apenure or orifice 50 adapted to spray a liquid or direct a fluid generally radially into and axially rearwardly along the support ring axial bore 27 or toward the gas turbine compressor 14. A suitable groove or recess 52 is formed in the support ring 26 adjacent each aperture 48 so that the liquid spray or fluid may be directed axially rearwardly of the support ring axial bore 27 or toward the gas turbine compressor 14 without support ring 26. v Each nozzle 38, 40 may be provided with an enlarged portion '55 which is sized larger than the aperture 48 was to preclude the nozzles from falling into the axial bore 27 and hence into the gas turbine inlet 12.
The liquid or fluid delivery means 28 has been shown as including an inlet fitting 54, a plurality of connecting blocks 56,
and a plurality of conduits 58 and 60 for directing fluid from the inlet fitting 54 to the connector blocks 56. The inlet fitting 54 is formed with a first inlet 62 and a second inlet 64 adapted respectively to be connected to a source of fluid (not shown) suitable for washing, preservation or power augmentation purposes.
Each connector block 56 is formed with a first and second central passage 66 and 68 respectively, a passage 70 adapted to communicate passage 66 with the nozzle support block passage 44, and a passage 72 adapted to communicate passage As best shown in FIG. 2, the conduits 58 extend around the support ring 26 and interconnect all connector block passages 66 with the inlet 62. The conduits 60 are arranged in like manner in axial spaced relationship to conduits 58 and interconnect all connector block passages 68 with, the inlet 64.
Each nozzle assembly 30, 32, 34 and 36 is securedto its respective connector block 56 and the support ring 26 with passage 44 communicating with connector block passage 70 and passage 46 communicating with connector block passage 72 by suitable fasteners 74. The fasteners .74 extend through oppositely extending lugs or ears .76 formed on each nozzle support block 42, through generally radially outwardly projecting ears 78 formed on the support ring 26, and into a suitable threaded portion (not shown) formed in each connector block 56.
A suitable gasket 79 may be interposed between each nozzle support block 42 and connector block 56 as shown in FIG.
4 to prevent fluid leakage.
A lug or ear 80 may be provided on the support ring 26 to which the inlet fitting 54 may be secured as at 82. As shown in FIG. 2, the inlet fitting 54 is preferably mounted to the support ring 26 with inlets 62 and 64 located radially outwardly of the conduits 58, 60 so that when the manifold spray assembly 22 is mounted to the gas turbine 10 with the fitting 54 down or at the bottom, the manifold spray assembly will be self draining.
The support ring 26 may be provided with a radially outwardly extending peripheral flange 84 at one or both ends which is adapted for use with a circumferential V-band clamp 86 of the type well known to those skilled in the art for removably securing the manifold spray assembly 22 to the gas turbine I0 and for mounting accessories such as an oil tank, Bellmouth or the like to the manifold spray assembly.
Although the spray means have been shown as comprising four generally equally circumferentially spaced nozzle assemblies 30, 32, 34 and 36 each having two nozzles 38, 40 extending therefrom, it should be understood that more or less than four nozzle assemblies may be used and that each nozzle assembly may have more or less than two nozzles.
The use operation and function of the invention are as follows:
The manifold spray assembly 22 is removably secured to the intake or forward end 12 of a gas turbine 10 using a circumferential V-band clamp 86. Preferably, the assembly is mounted with the inlet fitting 54 down so that the assembly will be self draining. Inlet 62 is connected to a source of washing and thrust augmentation fluid while inlet 64 is connected to a source of preservative fluid. When it is desired to wash the interference from the gas turbine 10 or augment thrust, fluid is directed from inlet 62 through conduits 58, through connector block passages 66 and 70, through nozzle support block passage 44 to nozzle 38. The nozzle orifice 50 then directs the fluid radially inwardly of the axial bore 27 and axially into the compressor 14. The four nozzles 38 are spaced generally equally around the manifold spray assembly 22 so as to provide a uniform spray of fluid throughout the gas turbine air intake 12.
When it is desired to apply preservative, preservative fluid is directed into inlet 64, through conduits 60, connector block passages 68 and 72, and noule support block passages 46 to the four generally equally circumferentially spaced nozzles 40 and hence radially inwardly of the axial bore 27 and axially into the compressor 14.
It should be noted that the nozzles 38 and 40 are recessed within the support ring 26 so as not to extend or project into and interfere with the gas turbine compressor intake airstream.
Although a preferred embodiment of the invention has been depicted and described, it should be understood that many addition, alteration, and variations may be made without departing from the inventions fundamental theme.
